True...

That's a SCSI hard disk, attached to the 29160?  Did you change any
hardware at the same time?  If you moved from one host adapter to
another, you probably have a geometry problem.

When you "boot off floppy and root from the hard drive", you're probably
loading the kernel from floppy.  You should be able to boot a floppy to
the boot prompt, then load the kernel from the hard disk:

  Boot
  : hd(40)unix

If that works, everything is in order except the geometry problem.

Once booted from floppy, go to single-user mode and run the following
commands.  The quotes are `backquotes` (unshifted "~" on most US
keyboards), and the '0' are zeros.

Write down any output from the commands, then continue with the next
command (even if the previous one failed).  Then reboot from the hard
disk.  This will not harm the system and _may_ help (though I suspect it
won't).

  # dparam /dev/rhd00
  # dparam -w /dev/rhd00
  # dparam /dev/rhd00 `dparam /dev/rhd00`

One other question.  Before you upgraded to 507 -- maybe _long_ before
-- did this system once have a different SCSI host adapter running the
root disk?

If you can, please answer all my questions even if the problem is
resolved somewhere along the way.  I'm chasing after a problem that I
think relates to yours and will I'll find all the details useful.

And, if it isn't fixed, don't panic.  That would mean that your problem
is closely related to what I'm chasing, and I hope to have a solution
soon...
